A lot happens in episode 21: the barrier falls, the invasion finally commences, and the plot grows ever more complex. At this point, I have very few worries for Kumoko, but so many for Shun and the elves. For an episode without Kumoko, it remains solidly entertaining, delivering plenty of food for thought to chew on here, especially with regards to the Administrators (but can we trust Oka’s information?). While I do miss Kumoko’s antics, it was nice to see the show shift gears and become a bit more action-oriented in a different direction. Though that’s not why I’ve stuck around; It’s the complexities of the plot, and all those juicy nuggets of worldbuilding, that keep me interested.
